. ch nes and more particularly to paper controlling devices.

Heretofore operators have experienced trouble at times in maintainingfree end portions of work sheets in the 'machine out of the path of theprinting instrumentalities,

or from falling forward and obscuring the scales or covering theprinting line. This is true when thin paper is employed, and especiallywhen there is a current of air in y the room, due to a natural breeze orto the use of a fan. In such cases those portions of the paper above theplaten, and out of control of the usual paper guiding devlces,

frequently drop, or are blown, forward anddownward so as to cover theprinting line, requiring the operator then to stop and replace the paperbefore proceeding with the writin One of the main objects of myinvention,

a generally stated, is to overcome these difficulties by providingsimple and efficient means operative on the free end portions of thework sheet or sheets to guide, 0011- trol and restrain them and preventthem from falling or being blown about in the machine and interferingwith its proper operation.

A further object of my invention is to provide means of the characterspecified in the nature of attachments that may be applied to existingmachines without modifying, or materially modifylng, the structuralfeatures of said machines as they now exist.

To the above and other ends which will hereinafter appear my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following description andparticularly pointed out in the appended claims.

.In the accompanying drawings wherein like reference characters indicatecorresponding parts in the various views,

Fig. 5 is an enlarged detail fragmentary sectional view showing themodified form of holding device in operative position.

Fig. 6 is a plan View of the blank from which a holding device of themodified form of construction is made.

I have shown my invention embodied in the present instance in a No.Remington machine in which the auxiliary paper holding device of myinvention may be read ily incorporated without modifying, or materiallymodifying, the structural features of said machine as they now exist.

The top plate 1 of the machine supports guide rails 2 oppositely groovedto receive anti-friction rollers 3 which are likewise received inoppositely grooved guide rails 4L of the carriage or truck 5, to supportthe latter in its travel over the top plate from side to side of themachine. A platen 6 is carried by a platen frame 7, connected byparallel links 8 and 9 to the truck for case shifting movement thereon,the platen frame being supported by its roller 10 on a shift rail 11 inthe usual manner.

The paper table 12 is carried by the platen frame, a work sheet apassing from the paper table to a paper apron 13, feed rollers 14 and 15and paper fingers 16. Each paper finger extends upwardly across theprinting line from a rock shaft 17 on which it is supported. Each shaftis mounted at its outer end in a bearing in the platen frame and at itsinner end in a bearing in a bracket plate 18 secured to a cross bar 19of the platen frame. As shown each shaft 17 is angular in cross sectionto receive a correspondingly shaped sleeve 16 of a paper finger, so thateach finger and the margin feed roller 20 carried thereby are supportedon their 'shaft to turn therewith and to receive an adjustment along thesame. The outer end of each shaft carries a finger piece 21 connected toa spring 22 by which the associate paper finger is normally held inoperative position with its margin feed roller bearing against theplaten or the.

paper thereon. I The parts as thus far described constitute a portion ofthe usual equipment of Nos. 10 and 11 Remington machines and while theattachments of my present invention may bereadily combined therewith itshould be understood that they may be employed in other combinations andarrangements and are not restricted to embodiment in a structure of thecharacter shown. 7

In the present instance I provide each of the paper fingers 16 with apair of supporting ears 23 that are connected together by and support apivot pin 24. Each socalled auxiliary paper controlling, guiding orholding device, arm or attachment is designated as a whole by thereference numeral 25. From an inspection of Fig. 3, which shows a blankfrom which one of these devices is formed, it will be seen that the mainbody portion '26 of the device is in the nature of a paper finger or armformed on each side with a flange 27 and a supporting ear 28, a tongue29 extending endwise from the portion 26 and beyond the cars 28. Eachblank is preferably struck up as shown with the flanges 27 extending inplanes at substantially right-angles to the body portion of the deviceto form stiffening or strengthening flanges. The ears 28 are bent up ina like manner, and are adapted to be received between the support ingears 23 on the associate paper finger, and to receive a pivot pin 24 inopenings 30 therein. The tongue 29 on each device is bent in betweenears 28 thereof to form two flat contact or engaging faces 31 and 32extending in planes at angles to each other. Each device may be curvedas shown in Fig. l, and is apertured at 33 to receive the associatemargin feed roller 20 when the device is in the operative position shownin full lines in this figure. A detent 34, which in the present instanceis in the nature of a leaf spring, is riveted at 35 to each paper fingerand the free end flat bearing portion thereof is adapted to bear againsteither of the contact faces 31 or 32 of the companion device 25,depending on whether said device is in the operative position shown infull lines in Fig. l, or is in the inoperative position shown in dottedlines in said figure. It will be. seen that whena device 25 is in theoperative position it is held by its detent over and adjacent to butfree from contact with the paper table. When theolevice is in thereleased and inoperative position it is held by its detent where it isout of the way and cannot, in its travel with the carriage, engage theusual fixed carriage pointer 36 or be interfered with by any part of themachine which would obstruct the movement of the carriage.

Referring to the modified form of construction shown at the right-handside of Fig. 4 and in Figs. 5 and 6, it will be seen that the guidingportion 26 of each device 25 curves inwardly toward the fore and aftvertical median plane of the carriage to coact with the work sheetthroughout a greater breadth thereof and therefore more effectively holdthe sheet and preventit from being blown forward. In this modified formof construction I so construct the parts that each device may bedetachably mounted on its paper finger, and may be readily attachedthereto or detached therefrom at will. Any suitable means may beemployed for this purpose. In the present instance each device 25 isformed with a bearing slot 37 which extends into the ears 28 and throughthe intervening body portion of the device. In mounting a device inposition the detent out of the way while the device is introduced intoposition with its pivot pin 24 seated in the slot 37 against the bottomwalls 38 thereof. The spring detent may then be it will tend to hold thedevice seated on its pivot, and in either the operative or inoperativeposition to which it may be turned on its pivot.

It will be understood that by carrying the auxiliary controlling deviceson the paper fingers in the manner shown and described said devices areshifted with the platen and platen frame in the case shifting movementsthereof, and are maintained in constant fixed relation to the platenduring such case shifting movements and during the travel of thecarriage, andin no manner interfere with such movements of the platenbut may always be in position to properly coact with the work sheet orsheets carried thereby. V 7

It will be seen, moreover, that the auxiliary devices extend from infront of the platen rearwardly over the latter and over the paper tableand adjacent thereto, where they act not only on the forward free endportion of the work sheet which extends beyond the printing line andplaten but also on the rear free end portion of the work sheet, whichhas not reached the platen, and prevent both such end portions frombeing blown forward into the path of the type bars 6 or to a point wherethe printing line is covered. 7 7

The devices of the present invention as shown are auxiliary or anaddition to the ordinary paper controlling devices includthan the device25,

spring is held to one side ing the paper finger l6, and act on portionsof the work sheet which for the time being are out of control of saidordinary controlling devices, and at such times are effective to preventthe portions in question of the sheet from being blown out of or awayfrom the proper course they should take in the machine.

In the Nos. 10 and 11 Remington machines each paper finger sleeve 16 isprovided with a forwardly extending stop finger 39, which is adapted tocoact with a stop finger 40 carried by a fixed portion of the machine.The purpose of these stops 39 and a0 is to prevent the paper guide 16from being brought into the path of the type bars I) should the operatorforget toset the margin and line lock stops according to the adjustmentof the paper guides. It will be seen that these stops not only areeffective to perform their usual functions but they also prevent theauxiliary guides from being brought into the path of the type bars Z)when, for example, such auxiliary guides are maintained in theinoperative position shown. in dotted lines in Fig. 1.

By carrying the auxiliary controlling devices in the manner shown anddescribed, they are rendered adjustable longitudinally of the platenwith the paper fingers and therefore enabled properly to act on the worksheets irrespective of the width of the sheet employed and theadjustment of the paper lingers. The auxiliary devices may be turned tothe inoperative position independently of and without interfering withthe paper fingers or guides 16 to perform their usual functions.Furthermore, the auxiliary devices do not obscure the operators view ofthe matter written on the sheet, while nevertheless overlapping thesheet to preventit from being blown forward, this being more especiallytrue of the first described device.

Various changes may be made without de- A parting from my invention andcertain features thereof may be employed without others.
